The board has large recording medium for erasable writings and drawings. A light source illuminates the surface of the recording medium. A photoelectric element converts the image of the writing and/or drawing recorded on the recording medium into electric signals. An image memory stores data corresponding to the electric signals. A printing head converts the contents of the memory into corresponding pattern signals and prints a pattern corresponding to those singals. Sheets of smaller size than the recording medium are secured to the recording medium.
